2 1/8-1 19/40

Make the mixed numbers into improper fractions

17/8 - 59/40

Make the fractions have the same common denominator

85/40 - 59/40

Subtract the numerators while keeping the denominators the same

Final Answer: 26/40 or 13/20

The area of the small shape is 35 square feet. The big shape is larger by a scale factor of 4/3. Find the area of the large shap

sdas [7]

Answer:

Option a) 62.2 square feet

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the large shape

y ----> the area of the small shape

$z^{2}=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=35\ ft^2$

substitute

$(\frac{4}{3})^{2}=\frac{x}{35}$

$\frac{16}{9}=\frac{x}{35}$

solve for x

$x=\frac{16}{9}(35)=62.2\ ft^2$

Use the relationship between the angles in the figure to answer the question. Which equation can be used to find the value of x?

Kaylis [27]

The sum of all the angles made by a straight line is 180°. Then the value of x is 61°.

<h3>What is an angle?</h3>

Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

The angles are shown on the diagram.

The angles are 52° and 67°. And let the other angle be x.

We know that the sum of all the angles made by a straight line is 180°.

Then we have

x + 52° + 67° = 180°

On simplifying, we have the value of x.

x = 61°

Thus, the value of x is 61°.

More about the angles link is given below.

Help and explain !!!!( Solve using the substitute method )

alex41 [277]

Answer:

x=13

y= -9

(13, -9)

Step-by-step explanation:

If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.

Then, we can take that equation and plug it into the bottom one so

3x+4(4-x)=3

Simplify:

3x+16-4x=3

-x=-13

x=13

We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)

So, 13+y=4 which y= -9
